Tent Hubble, 564 -4628 Well Number Permit No. / Approval No. Drilling Engineer: Phil Smith, 564 -4897 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection, Water Injection, Water - Alternating -Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI (Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50 -029- 20123 -00 -00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain). Item 28: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071.

Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. Item 1 a: Classification of Service Wells: Gas Injection, Water Injection, Water - Alternating -Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. Item 4b: TPI (Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits (ex: 50- 029 - 20123- 00 -00). Item 20: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain). Item 28: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 MC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 MC 25.071.

MIT -IA to confirm injection rate /pressure for the documented PC leak at 6830' MD (DONE 2 BPM AT 1000 PSI / 1 BPM AT 800 PSI - 10/20/09). MIT -OA w /diesel to 2000 psi (expect to fail) (TEST FAILED ON 10/18/09). S . (CANCELLED REQUEST ON 10/21/09 - HOWEVER, GYRO WAS RUN ON 10/20.) S 4. Pull the IBP from 9345' MD in preparation to P &A perforations. F 5. Confirm injectivity into the open perforations as required for the cement work to follow.

WOC to 500 psi compressive strength and pressure test the cement plug to 2500 psi. E 7. Drift for tubing for planned tubing punch to 9300' MD. E 8. Punch tubing at 9300' MD and circulate the well to 9.8 ppg brine. i E 9. Jet cut 4 -Y2" tubing at 4500' MD ( -2' below nearest tubing collar). F 10. Circulate well to 9.8 ppg brine thru the tubing cut & freeze protecting the top 500' of the well with diesel. W 11. Bleed IA and T to 0 psi. W 12. PPPOT -T to 5000 psi, PPPOT -IC to 3500 psi. Function tubing and casing lock down screws. Repair and replace as needed. ✓ 13. Set a BPV in the tubing hanger. Secure Well O 14. Remove the well house and flow line. Level the pad as needed for the rig. Provide total well preparation cost on the handover form. Proposed Drilling Rig Operations: 1. MI /RU and confirm wellhead pressures at 0 psi. 2. Pull BPV w/tested lubricator and circulate out diesel freeze protection and displace the well to 9.8 ppg brine. 3. Re -set BPV and to 1000 psi from below (this will be a rolling test due to known PC leak). 4. As the 7 -5/8" production casing will be cut and pulled on this well, begin the OA monitoring process (un- cemented annulus / RU to bleeder tank and bleed the OA to 0 psi). 5. Nipple down tree and insert a blanking plug and test from above to 3500 psi per FMC rep. Nipple up and test BOPE to 3500psi. (NOTE: INSTALL SPACER SPOOL ABOVE THE TUBING SPOOL IF / REQUIRED TO ALLOW THE TESTING OF THE LOWER SET OF RAMS PRIOR TO PULLING THE TUBING.) 6. Pull the blanking plug and BPV w/tested lubricator per FMC. 7. R/U & pull 4 -1/2" tubing from the cut depth at 4500' MD. 8. PU drill -pipe and make bit and scraper run to the top of the tubing stub. 9. RU E -line and run GR/CCUUSIT log from top of the tubing to surface to confirm P2 -31A 11/4/2009 8 10. With E -line, run and set an EZSV just above the tubing stub at -4062' MD and test well to 2500 psi for 30 minutes and chart. (NOTES: 1. - The PC leak should be buried below the EZSV at this point. 2. - This EZSV will represent a 2" barrier in the well between the PC leak and surface if needed for path - forward work.) 11. MU Baker 7 -5/8" casing cutter and RIH to the top of the EZSV at -4062' MD and circulate the well to clean seawater/fresh water. 12. Pull the casing cutter up to 3862' MD ( -75' below the surface casing shoe) and cut the 7 -5/8" casing and circulate the annulus to seawater/fresh water. (NOTE: Be prepared for -100 bbls of diesel freeze protect coming back during the OA circ -out.) 13. With sufficient down -hole barriers in place, pull the 7 -5/8" casing from the cut at -3862' MD through the wellhead/BOPE per FMC. 14. RIH with open -ended drillpipe and diverter and lay a balanced cement plug from the top of the 7 -5/8" EZSV at 4062' MD back into the 10 -3/4" casing to -3487' MD ( -575' cement plug). NOTE: If the 7 -5/8" casing cannot be pulled from -70' below the 10 -3/4" surface shoe, the 7 -5/8" casing will be cut just inside the 10 -3/4" shoe and a whipstock departure from the 10 -3/4" casing will be back -up plan for sidetracking this well (will require a CIBP at base of 10 -3/4" casing to accommodate a casing test).
